To all whom it may concern:

'Be it known that we, VICTOR R. BROWN- ING and EARL H. BROWNING, residing at N ettingham, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Hoisting Mechanism, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

Our invention relates to the hoisting mechanism of locomotive cranes and the like, and has for its general object the provision of means whereby the various parts of the hoisting mechanism may be conveniently assembled and disassembled and to the construction of parts whereby such assembling and disassembling is rendered possible.

The mechanism illustrated, described and claimed herein is a division of our application 242,849, filed Jan. 27th, 1905.

Generally stated, the invention may be defined as consisting of the combinations of elements embodied in the claims hereto annexed.

Figure 1 represents a sectional view taken through the housings ust forward of the engine shaft, the lever brackets being shown in elevation and the operating levers being removed for clearness of illustration; Fig. 2 represents a similar section at right an les to the plane of Fig. 1, showing some of the operating levers; Figs. 3 and 4 represent respectively an end and a side elevation of one of the side housings; Fig. 5 represents an enlar ed sectional view on the line 5-5 of Fig. 4; ig. 6 represents a detail showing the manner in w ich access may be had to the shafting carried by the housings; Fig. 7 represents a front elevation of the boom hoisting drum.

1 represents the floor frame of a locomotive crane, said frame being provided with the depending integral hubs or sleeves 2 and 3, the former being provided for the reception of the journal 4 of the shaft 5, the lower end of which carries the pinion 6 by which the floor frame and the parts supported thereby may be rotated. The upper end of shaft 5 is provided with the bevel gear7 meshing with the bevel pinion 8 on a horizontal shaft 9 which is driven from the main or engine shaft 10 through the bevel gears 11 and 12. The hub or sleeve 3 supports a journal 13 for a vertical shaft 14 by which the crane is driven along the track The upper end of this shaft is provided with a bevel gear 15 meshing with a bevel gear 16 on the counter-shaft 17. The shaft 17 is driven from the shaft 10 by means of the gears 18 and 19 on said shafts respectively and the clutch 20.

21 denotes a counter-shaft which is driven from the shaft 17 by means of gears 22 and 18 on said shafts respectively. (See Fig. 1.) Shaft 21 is provided with a bevel gear 23 and clutch 24, by means of which and the bevel gear 25 the motion of the shaft 21 may be transmitted to the vertical shaft 26. Shaft 26 is provided with a worm 27 engaging a worm gear 28 on shaft 29 which carries the drum 30 for hoisting and lowering the crane boom.

31 desi 'nates the hoisting drum mounted on a sha't 32 which is operated from the shaft 17 through the reduction gears 33 and 34 and clutch 35 (see Figs. 1 and 2).

The details of the means for driving and rotating the crane need no detailed description here, the same being shown, described and claimed in our application 242,849, hereinbefore referred to.

Bolted to the floor proper of the frame 1, adjacent each edge of the same, are the housings 36. These housings support the engine shaft and most of the horizontal counter-shafts by which the various mechanismsof the crane are operated. Extending between these housings, near the upper front portions thereof, is the hollow frame or separator 37. This frame or separator is secured in place by bolts 38 (see Fig. 1). The engine shaft 10 and the counter-shaft 17 are supported in bearings 39, 40 formed in the lower portion of each of the housings. The front edge of each of the housings is inclined, as appears in Fig. 4, and in each inclined edge are formed a support 41 for the boom-hoist shaft 29 and a split bearing 11" for the hoisting drum shaft 32. The horizontal counter-shaft 9 which operates the shaft 5,is supported by the pillow blocks 42 and is driven from the engine shaft 10 in the manner hereinbefore described.

The housings are particularly constructed with reference to the ease of assembling and disassembling the shafting. Each of the said housings is provided near its lower edge with a recess 13 extending from the rear edge thereof to the vertical rib 44, from the upper portion of which the inclined rib 15 extends which carries the bearings 41 and 41 for the shafts 29 and 32. The strengthening rib 46 i bounds the lower portion of the recess and is bers arelocked together.

provided with the bearings 39 and 40 for the shafts 10 and 17 respectively. The bearings for these shafts are of the ordinary split type and are provided with removable caps 47 and 48 respectively. A strengthening rib 44 extends between rib 44 and bearing 41*.

The housing above the recess is provided with a rib 49 which merges at its rear end with a sleeve 50. The corresponding lower rib 46 merges with the sleeve 51, both of said sleeves being in vertical alinement. A rearwardly and downwardly inclined rib 52 ex tends from the rear end of the rib 46 to the base of the housing. A removable sleeve 53 having a corresponding inclined rib 54 is adapted to be inserted between the sleeves 50 and 51 to form therewith a continuous ribbed sleeve for the reception of a bolt 55. This boltis provided at its upper end with a screw-threaded portion 56 and near its lower end with a slot 57. A corresponding slot 58 is formed in the sleeve member 51 for the insertion of a key or locking-pin 59. This key or locking-pin is provided with bottom lugs 60 and an intermediate recessed portion 61.

To assemble the'shafts 10 and 17, they are inserted into the recesses 39, 40, respectively,

"and are secured in place in their bearings,

after which the sleeve member 53 is fitted between the members 50 and 51, the bolt 55 is inserted, the key or locking-pin 59'is inserted in place and, by means of a nut 62, the bolt is tightened up 'and the-sleeve mem l/Vhen it is desired to disassemble the shafts 10 and 17, the nut 62 is slacked up, the locking-pin 59 removed, whereupon the sleeve member 53 may be taken out and the said shafts may then be withdrawn through the recesses of the housings.

The hoisting-drum 31, with its shaft, may be readily removed by unscrewing the journal caps 63 and disconnecting the brake bands 64. This brake band being bolted at one end to the rod 65 extending through the frame or separator 37, it is only necessary to unscrew the nuts'66 from the upper end of said rod to disconnect or slacken up the brake and permit the easy removal of the hoisting drum and its shaft.

The boom hoisting apparatus comprises the horizontal counter-shaft 21 j-ournaled in the lower end of brackets 67 integral with and depending from the frame or separator 37, the vertical worm shaft 26 driven from the shaft 21 and the worm 27 within the frame or separator 37 engaging the worm gear 28 011 the boom hoisting drum, the rear portion of which gear is within said casing or separator. The worm shaft is provided with bushings 68 and 69, the former being journaled in the bottom of the separator 37 and the latter being journaled in a sleeve 70 I which is removably fitted in an opening in the upper end of the said frame or separator. The lower end of the shaft 26, outside the beveled gear 25 is removably secured to such tapered portion by means of a nut 71. A pinch collar 72 surrounds the worm shaft, just above the worm, and is operated by means of the hand wheel 73 and shaft 74, to brake the worm shaft in a well known manner. The brackets 67 are in line with the brackets 75 when the latter are in place in the crane.

The worm gear is inclosed by means of an integral extension 76 of the frame or separator, the said frame and extension inclosing about half of the worm gear. The removable casing 77 completes the inclosure of said worm gear. On each side of the worm gear, outside of its casing, extends the drum 30 for the cable by which the boom is raised and lowered (see Fig. 7). The drum is provided with journals 78 within which are bushings 78. A shaft 29 rotatably supports the drum, said shaft being carried by the bearings or supports 41, in which it is secured by a driving fit. The drum is removed by driving or forcing the shaft 29 on which the drum 30 is sleeved longitudinally through the drum and through the ring bearings 41. After the shaft has been withdrawn, the drum may be lifted out or otherwise removed.

In order to remove the worm gear and its shaft, it is only necessary to remove the easing extension 77 and drive the shaft endwise through the drum in which it is ournaled,

withdrawn. To remove the worm and its shaft, it is only necessary to unscrew the hand wheel 73 until the pinch collar is dis- 71 and remove the bolts 79 securing the sleeve or ournal 70 to the frame or separator 37, whereupon the worm and its shaft, together with the sleeve or journal 70, may be lifted out of the casing or separator.

The end of the brake band 64 which is opposite'the end connected with the brake rod is connected to the same sleeve 82 as hand lever and foot lever 81, whereby said brake may be applied by hand or foot power or both (see Fig. 2). This sleeve is mounted in a shaft 83. supported between the lower end of one of the brackets 75 and the opposite portion of the adjacent housing, the opening 84 being provided in said housing for this purpose. Where a double hoisting drum is employed, a similar shaft, brake and lever may be employed on the other side of the machine, the brake-lever shaft being sup- In Fig. 1, an opening hand housing for the and a sleeve or bearengaged by the shaft 74, to unscrew the nut frame or separator 37 is tapered, and the whereupon the drum and worm gear may be ported by the corresponding bracket and 4 ing 85 is shown as provided for the reception of a brake rod similar to 65, but said shaft, operating levers and brake are omitted for clearness of illustration.

As will appear from Fig. 2, the hoisting drum shaft is supported out of line with and in front of the frame or separator37. This gives an inclination to the brake rod 65. To

accommodate this inclination, a long slot 86 is provided near each side of the front wall of said frame or separator and the upper surface of said frame or separator has cast therewith the integral bearings 85, said bearings having each an inclined bore to correspond to the inclination of the rod 65 and the upper surface of each of said bearings being at right angles to the axis of the bore to provide suitable bearings for the adjusting nuts 66. The other end of the brake band, as hereinbefore explained, is connected to the sleeve 82, which is mounted on the shaft or rod 83 in front of and below the frame or separator 37.

The brackets 75 are for the purpose of supporting the shafts and quadrants of the various levers by which the brake and clutches are operated, but illustration and description of the clutch-operating levers are omitted from this application, the same forming part of the subject matter of another application, also a division of application 242,849 filed Jan. 27, 1905. In Fig. 2, there is shown a quadrant 87 for the hand lever 80 which operates the brake band.

. conveniently assembled and disassembled,

a very important factor in the construction of an effective and economical machine of this character.
